UNDERFRAME FOR CARS.

specification of Letters Patent.

Patented Feb. 18, 1909.

Application filed May 12, 1908. Serial No. 432,485.

To all whom it may concern:

Be it known that I, ANTON BECKER, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Underframcs for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in underframes for cars, and more particularly for use with cars in which the superstructure is supported upon the pedestals,such for instance as cabooses.

The object of my present invention is to provide simple and eflicient means whereby an underframe comprising a center girder and transverse members, can be readily supported through the medium of devices secured to said transverse members and mounted upon and secured to the car pedestals.

A further object is to construct such an underframe in a manner to effectually support the side sills of the car at points beyond the support of said underframe upon the car pedestals, and to facilitate the supporting' of furring strips upon which the car flooring is located.

W'ith these objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accom anying drawings, Figure 1 is a plan View 0 portion of a car underframe with the cover plate 4 removed embodying my improvements. Fig. 2 is a transverse sectional view, and Fig. 3 is a view on the line a2m of Fig. 2. 1 represents a center girder which may consist of two channel irons spaced apart and having suitable bracing means 2 be tween them, but so far as my present invention is concerned, this center girder may be differently constructed.

Near respective ends of the frame, trans verse members or cross beams 3 are located, and so spaced apart as not to interfere with the car wheels, the pedestals for which are connected with these cross beams as hereinafter explained. Each cross beam consists, at respective sides of the center girder, of

two channel iron members secured at their inner ends to the center girdcr for which purpose said cross beam members may be provided with flanges 3 bolted to the center girder. It is evident that the cross beam members at one side of the center girder cooperate with those of the other side for the purpose of forming the cross beams. .t compression plate 4 is secured at its side edges to the respective cross beams and, extending across the center girder, terminates inwardly of the ends of the cross beams. Similarly, a tension plate 5 is disposed under the center girder and is secured at respective sides thereof to the lower flanges of the respective cross beams. The outer ends of the cross beams are provided with depressed seats 6 for the accommodation of side sills 7 At suitable intervals between the pairs of cross beams above described, other transverse members or cross beams 8 are located and these may consist of diaphragms having lateral flanges and the respective members of each cross-bearer are secured at their inner ends to the center girder and between the members of the latter a brace 9 may be located. This brace 9 and the inner ends of the cross-bearer members are secured in place by means of bolts passing through flanges on said braces and flanges at the inner ends of the cross-bearer members. A top plate 10 extends across the center girder and is secured to the upper flanges of the cross-bearer members. The outer end of each cross-beam is provided with a depressed seat 12, which seats cooperate with the seats 6 of the beams 3, to support the side sills 7. The cross beams 3 and 8 also cooperate in supporting a series of furrinfl strips 13, the upper faces of which aline with the upper faces of the side sills for supporting the car flooring.

Inwardly removed from the outer ends of the cross beams 3 and between the separated members composing said beams, a flanged plate 14 is located. This plate is provided at its side edges with flanges 15 which are bolted to the respective cross beams 3 and at its lower edge, a flange 16 is provided. The plate 14 is thus so located that it will be disposed directly over a car pedestral 17 and rests upon a flange 17 of the latter. The plates 14 thus provide supportin means or connections for the underframe with the pedby the car pedestals and that the side sills are supported upon the transverse members outwardly beyond the support of the latter upon the car pedestals.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. A. car underframe comprising a center girder, transverse members and attaching means for a car pedestal secured to said transverse members.

2. A car under-frame comprising a center girder, transverse members secured thereto and affording supports for side sills, and plates secured to said transverse members for supporting the underframe upon a car pedestal.

3. A car underframe comprising a center girder, transverse members, and means secured to said transverse members and adapted to be secured to the pedestals of a car.

4. A car underframe comprising a center girder, transverse members provided at their outer extremities with seats for side sills and plates secured to said transverse members at points inwardly removed from said side sill seats and alfording means for supporting the umlerframe upon the pedestals of a car.

5. A car underframe eomprisin a center girder, cross beams each comprising members spaced apart, and flanged plates secured between said members and affording means for securing the under-frame upon the pedestals of a car.

(3. A car underframe comprising a center girder, transverse members spaced apart, plates secured between said transverse members, each of said plates having a flange at its lower end, car pedestals to which the flanges at the lower ends of said plates are socured, and fastening means passing through said plate and the car pedestals.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
